ukb-skill SKILL.md skillA

ukb-skill from cuhk-aim-group/neurodiscovery is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add cuhk-aim-group/neurodiscovery/ukb-skill@git:20260506.86420c0

Pins git:20260506.86420c0 in mdr.lock. Pin the fingerprint instead.

Use this skill whenever the user wants to analyze already available UK Biobank data for brain-related research, including neurological outcomes, cognitive phenotypes, brain MRI derived phenotypes, survival analysis, subgroup analysis, propensity score analysis, mediation analysis, sensitivity analysis, machine learning, visualization, or manuscript-ready summaries. This skill only covers post-extraction analysis and explicitly excludes RAP access and data download guidance.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# UKB Skill (Dataset Layer)

## Overview

`ukb-skill` is the NeuroClaw **analysis-layer** skill for **brain-focused UK Biobank downstream research**.

This skill is designed for users who already have local UK Biobank tables, derived phenotype tables, or neuroimaging-derived feature matrices and want to run downstream statistical or machine learning analyses.

It follows the NeuroClaw hierarchical design principles:
- This skill describes **WHAT needs to be analyzed** and **which existing skill should handle each part**.
- It contains **no RAP download workflow** and **no cloud export instructions**.
- It contains **no direct implementation code** and **no direct shell commands**.
- All concrete execution should be delegated through `claw-shell` and related downstream skills.

**Core workflow (never bypassed):**
1. Confirm that the user already has accessible UK Biobank-derived local data.
2. Identify the research target: neurological endpoint, cognitive phenotype, brain MRI phenotype, or predictive modeling task.

How to install

The exact contents, by fingerprint

mdr add cuhk-aim-group/neurodiscovery/ukb-skill@sha256:dc39a35eb60e5b39

The line at the top of this page pins the label git:20260506.86420c0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
